Practical workflow for reducing token usage in Claude Code while preserving session continuity. Includes compacting strategies, CLAUDE.md structure, modular context management, and prompt engineering tips.

🧠 How to Save Context Tokens When Using Claude Code

This is a personal reference workflow for minimizing token usage while maintaining project continuity across Claude Code (Sonnet 4 with file access).

✅ Setup: Populate CLAUDE.md

Claude loads CLAUDE.md automatically at session start.

Build images directly into the K3s containerd instance with BuildKit

I wanted to iterate on some images and have them available to K3s immediately, much like the Docker Desktop experience.

I also wanted to use docker buildx bake for this, but buildctl and nerdctl build should work fine too. You can omit Docker components if you don't want Buildx.

  • Ubuntu 22.04
  • K3s latest (v1.24.2+k3s1)
  • BuildKit v0.10.3
  • Docker Engine 20.10.17 (required for Buildx)
  • Docker Buildx master (required for new 'remote' driver)
  • Nerdctl 0.21.0

Powershell Native crlf and lf Functions
<#
switch between crlf and lf much like unix2dos and dos2unix but implemented in powershell.
put two functions into your $PROFILE and call like the following:
default params is your current working dir and ignoring .git and vendor dirs
crlf file.txt
crlf ./dir @(".git", "vendor")
lf file.txt

Packer with WinRM over HTTPS

Way to build Windows STIG/CIS hardened AMI on AWS.

Problem is that WinRM Basic authentication is blocked by GroupPolicy.

Therefore it's required to setup WinRM over HTTPS.

Fix DNS resolution in WSL2

Permanent WSL DNS Fix (WSL 2.2.1+)

If you're encountering ping github.com failing inside WSL with a Temporary failure in name resolution, you're not alone — this has been a long-standing issue, especially when using VPNs or corporate networks.

This issue is now fixed robustly with DNS tunneling, which preserves dynamic DNS behavior and avoids limitations like WSL’s former hard cap of 3 DNS servers in /etc/resolv.conf.

DNS tunneling is enabled by default in WSL version 2.2.1 and later, meaning that if you're still seeing DNS resolution issues, the first and most effective fix is simply to upgrade WSL. Upgrading WSL updates the WSL platform itself, but does not affect your installed Linux distributions, apps, or files.

To upgrade WSL, follow these steps,
